ze_chaz 0 Report post Posted February 15, 2009 Hi there, a couple of questions Dad wants me to do a service on his wagon. I had a E34 525i of my own but thought with the later engine, dads wagon might require some things done differently. I work for BNT so part availability is no problem. Car: E39 528I Year: 2001 Kms: 78,000 First off, does anyone know what grade of oil to use, how much I will need, and should it be fully synthetic? Secondly, how can I tell if the transmission fluid will need changing or is it a lifetime type fluid? Anything I should watch out for when servicing it and what might be different from my E34? Thanks in advance. Quote Share this post Link to post Share on other sites
*Glenn* 854 Report post Posted February 16, 2009 ELF recommend 10w40 semi synthetic youll need 7.25-7.5 litres If the trans has longlife oil you will need to change it @ 100,000km. You can do it earlier if you want with new filter and pan gasket...you will need between 4-5litres if changing the filter and allowing it to drain for half an hour to allow the torque convertor to drain. The oil type will be on a sticker on the pan. Unless you have the correct type of filler (done from underneath the car) and your not sure how to do it....get a professional to do it for you. The transmission will take either G3 full synthetic or G3LL full synthetic (longlife or ESSO oil) Quote Share this post Link to post Share on other sites

And to be clear, will our fuchs titan super GTO 10w-40 be suitable? I mean I know oil can't do that much damage but I want to be safe seeing as it is not my car I'm putting it in.

So long as its semi synthetic 10w40 it should be fine Quote Share this post Link to post Share on other sites
ze_chaz 0 Report post Posted February 16, 2009 Thanks you have been very helpful. I have found out the only semi-synthetic we do is 15w-40. Am I correct in assuming there is not a massive difference between 10w-40 and 15w-40? Quote Share this post Link to post Share on other sites
